1 Claim. (Cl. 103211) This invention relates to improvements in a the pipe 15, thus permitting convenient assembly pressure pump, the primary object being to proof the co-operating parts, the pipe 22 extends upvide a type of pump which eliminates the heavy. wardly past the well platform 23 and turns to manual practice of pumping, this being accomterminate in the outlet nozzle 24. The pipe 22 plished by employing a heavy weight of circular is further provided with the lead pipe 25 for house 0 proportion which snugly engages the sides of a or any underground lead and a suitable shut-off well exerting a downward pressure on the water valve 26 is positioned above the well platform. which results in the water rising upwardly For purposes of raising and lowering the weight through a centrally located pipe. 13, a Windlass 27 is mounted above the well plat- A further object is to provide a type of pump form and suitable steel cables 31 extend from 5 which employs a Windlass having an elongated each end of the Windlass downwardly to eye bolts leverbar with ratchet attachment for raising the 28 Which are firmly secured diametrically of the pressure weight. weight 13.
